ALBERT N. WOODRUFF, OF NEW YORK, N. Y.

COPY-HOLDER.

Application filed July 29,

To all whom t may concern Be it known that I, ALBERT N. WOODRUFF, acitizen of the United States, and a resident of the city of New York,borough of Manhattan, in the county and State of New York, have inventeda new and Improved Copy-Holder, of which the following is a full, clear,and exact description.

The present invention relates to new and useful improvements incopy-holders, and it pertains more particularly to a device forsupporting in a visual position, stenographers note-books, and othercopies.

It is the primary object of the present inventionA to provide acopy-holder with a marker, which marker is movable with respect to thecopy carried by the holder.

It i's a still further object of the invention toprovide new and novelmeans by which the movement of the marker may be adjusted to steps ofvarious lengths.

With the above and other objects in view, reference is had to theaccompanying drawings, in which- Figure 1 is a front elevation of acopyholder. constructed in accordance with the present invention; f Fig.2 is a rear view with a portion of the mechanism broken away;

Fig. 3 is a side elevation of the copy-holder constructed in accordancewith the present invention;

Fig. 4 is a detailsectional view taken on bed 10, is a screw-threadedrod 30, and' said the line 4--4 o-f Fig. 2, and

Fig. 5 is a detail sectional view taken on the line 5 5 of Fig. 1.

.Referring more particularly to the drawings, the device comprises awriting bed 10, carried by a support which consists of a pair of basemembers 11 having angularly disposed rear legs 12, and pivotally securedto the writing bed 10, as at 13. The forward ends of the base members 11are looped and bent upwardly to provide legs 14. f

Pivotally carried by the looped portions ofthe base members 11, is asupporting bracket 15, substantially U-shaped, and the looped portion ofsaid 4Ushaped bracket 15 is adapted to engage beneath the forward end ofthe writing bed 10 to support the latter in inclined position. Each ofthe legs of the `U-shaped member 15 is coiled about the looped portionof the base 11 as indicated by the reference character 16, and said legsare Y.further provided with hooks 17 adapted Specification of LettersPatent. Patgnted Aug, 30, 1921,

1920. Serial No. 399,672.

to engage the legs 14. of the looped portions of the base members 1 1 tolimit the movement of the U-shaped member in one direction.

To provide for securing a. copy-book 18 in place on the writing bed 10,a clamping member 19 is employed, and said clamping member comprises asubstantially L-shaped member, the legs of which are slidable in guides20 carried by the writing bed, as more clearly shown in Figs. 1 and 2.The long leg 21 of the L-shaped clamping member projects parallel withone ofthe side edges of the writingbed 10 and is provided on its rearend with an operating button 22, and secured to this operating button 22and projecting inwardly of the writing bed 10, is a guide member 23.

Secured to the rear end of the writing bed 10, as` by means of a clip 25and a bolt or lscrew 26, is a spring member 27, and said spring member27 has two legs 28 and 29. The leg 28 of this spring member 27 engagesthe operating button 22 of the L-snaped member 19 to maintain the sameextended in order that clamping action may be had on the copy-book 18.By this construction, it will be apparent that as the operating button22 is forced against the action of the spring 27, the L-shaped clampingmember 19 will be released from the copybook and the same will be freeto be removed.

Rigidly secured to the rear of the writing screw-threaded rod 30 extendsthroughout the length of the bed and is rigidly secured to the endsthereof as by means of collars or nuts 31. To fill the space between thescrewthreaded rod 30 and the writing bed 10, a plate 31 is interposed,as more clearly shown in Fig. 4. Extending longitudinally of the bed 10on its rear face in parallelism to the screw-threaded member 30, is ascrewthreaded member 32, said member being reciprocatively mounted withrespect to the writing bed 10. This member 32 has one of its endsprojecting beyond the end of the writing bed 10, as indicated bythereference character 33and said projecting end is provided on itsextremityv with an operatingy button 34C. This screw-threaded member 32is rigidly carried by means of a flat plate 35, and said flat plate 35is slidingly mounted between guides 36 and v37 carried on the rear faceof the wrtingbed 10.V To maintain the reciprocating threaded member 32in extended position, the leg 29 of the spring member 27 is bentthereabout as indicated by the reference character 38, and interposedbetween the operating button. 34 or the screw-threaded member 82 and theend ot the writing bed 10, is an adjustable nut 40, by means of whichthe stroke of said reciprocating member may be limited or regulated.

The reference character 45 designates the marker, which comprises apiece ot wire looped as indicated by 46, in order thatj` it may passaround behind the writing bed 10. As shown on F ig. 2, this loopedportion 46 of the marker 45 is mounted in clips or bearings 47, and saidportion is again looped as indicated by the reference character 48 toprovide an arm 49, which overlies thetwo screw-threaded members 30 and32. The clips 47 in which the marker is journaled are mounted on acarriage 50. One end of the carriage 50 is projected beneath a flange 51formed on one side edge of the writing bed, as indicated at 52. Theopposite end of the carriage 50 is provided with a guide 24, said guidecomprising two plates arranged in rightangular relation to each other insuch a manner as to provide a member crossshaped in cross-sectionalform. yOne of the arms of the cross projects between the long leg 21 ofthe L-shaped member, and the other member having two spaced arms 53which overlie the long leg 21 of the L-shaped member as shown in Fig. 1.

To maintain the marker 45 at all times in contact with the copy, a coilspring 54 is provided, said coil spring having one of its arms 55exerting a pressure against the leg 49 of said marker.

Mounted on the carriage 50 are two pivoted dogs 56 and 57. These dogs 56and 57 are adapted to engage the screw-threaded members 32 and 30,respectively, and to maintain them in engagement with theirscrew-threaded members, a coil spring 58 is employed.

r1`he device operates in the following manner:

lith the parts in the position shown in Figs. 1 and 2, when it isdesired to move the screw-threaded member 32, the pivoted dog soV 56engages the flanges ot' said screw-threaded member and upon saidscrew-threaded member 32 returning to normal position, under theinfluence ot the spring 29, the carriage will be moved with it. The dog57 prevents the movement 0f the carriage wht/11th@ screw-threaded member32 is depressed but permits ot a free movement of the carriage when thesame is moved by a reciprocation ot the screw-threaded member 32, sincewhen moving inthis direct-ion the dog 5T slides ireely over thescrew-threaded member 5l).

When it is desired to position the marker at the top ot the writing bed10 in order to start a new sheet on the copy, it is only necessary tograsp the looped portion 46 thereof, and rock it in its bearing clips47. This action causes the looped end 49 of the marker to engage thepivoted dogs 56 and 5 7 and rock them about their pivotal point to aposition where theydisengage their respectivey By adjustment oit the nut40, it will be :ip-

parent that the stroke of the screw-threaded member 32 may be varied andthat as the stroke is varied, the distance of movement of the marker 45will likewise be varied, thus adapting the device for use in connectionwith copies having varying spaces between the lines ot writing thereon.

From the foregoing it will be apparent that the present inventionprovides a new and improv/ed copy-holder by means of which the operationof copying is greatly facilitated, and, at the same time, a device isprovided which is simple in both construction and operation.
